Even if PHP is being surpassed by Node and Rails, the typical users of the CMS don't care. Wordpress does what it is supposed to do very well, and the typical (non-technical) end-user just doesn't care (or understand) what technology it is based on. Now, if you design a "better" (I'm not sure what that means, but you seem to know) CMS, would you be able to take away WP's market share? Probably yes. Does it matter what language the product is written in? Not directly. It only helps you indirectly in that the technology may be able to help you build a better product faster, or allow for new features that aren't easily implemented with PHP. Why hasn't somebody done this? My personal guess is because it would take a lot of time (=money). Wordpress has gazillions of features and is very polished.
